快走丝切电火花线割机床割铝装置的设计

快走丝电火花线切割机床切割铝件时出现导电块磨损严重、电极丝与导电块之间有电火花产生、断丝现象频繁等不良现象,严重影响了铝件的表面加工质量和加工效率。首先分析了线切割机床切割铝件时产生上述不良现象的原因;然后通过改变原有的导电块导入脉冲电源负极的方式,采用储丝筒导入脉冲电源负极的方式,并设计了专用的脉冲电源负极导入装置,确保电极丝与电源的可靠接触;最后通过实验验证了设计方案的可靠性和正确性,为铝件的切割加工提供了技术支持。

Design of a special cutting aluminum device on WEDM-HS

When wire electric discharge machining with high speed(WEDM-HS)is cutting aluminum parts,some cosmetic defects may occur such as severe wear of conductive block,sparks occurrence between wire electrode and conductive block as well as broken wires,which may impact surface quality severely of the aluminum pieces and working efficiency.First reasons for the above defects during cutting the aluminum parts are analyzed in it,then a special impulse power cathode leading-in device is designed through changing orig...
